Is this your Dockerfile or are you using Railpack?

About the incompatible node version, nixpacks defaulted to node 18 when I first deployed to railway. Find a way to maybe either specify node version for nixpacks if that's possible or use dockerfile deployment
I could help you with that if I had more information about your project and structure.

its the default dockerfile from railway, so i assume it is railpack

where should i start regarding the nixpacks?

Based on the error message you provided, the problem is very clear: the minimatch@10.0.3 package requires Node.js version "20 || >=22", but your current environment (likely inside a Docker container) is using Node.js version "18.20.5".

Quickest way would be to set the env NIXPACKS_NODE_VERSION to 23 as specified here : https://nixpacks.com/docs/providers/node

Then rebuild. Make sure you go check the build details to see if railway is actually using the env during build time because we don't need this env on runtime just build time
On runtime it will simply be ignored

tried this, didnt work and it ended up using 18 during build

thanks for the help everyone, i decided to use railpack and it worked, i tried changing node version via env for nixpacks, couldnt get node version 23 to work

Kind of expected that, hence the second reply about actually checking it.
Happened to me too, railway needs to be told to use the env during build time and won't supply it as it is

I don't know how to supply that when using nixpacks but the link i gave also mentions other ways to specify the node version and one of the ways is doing it in your package.json file

If you need the actual code to be inserted into package.json, it's just this

{

"engines": {

"node": "23"

}

}
